NUMERAL-WHEEL SUPPORT FOR ADDING-MACHINES.

Specification of letters Patent.

Patented July 29, 1913.

Application filed July 22,1908. Serial No. 444,836.

To all whom it may concern:

Be it known that I, HENRY KiiN'rznnR, a citizen of the United States, and resident of Kingston, Luzerne county, Pennsylvania, have invented certain new and useful Im provements in Numeral-Vvheel Supports for Adding-Machines, of which the following is a specification.

My invention relates to numeral wheel supports for adding machines, and its novelty consists in the construction and adaptation of the parts as will be more fully hereinafter pointed out.

The machine to which the invention is specifically adapted is the well known Vales adding machine, in Which, in the usual operation of the machine, itis necessary to lower the numeral wheel shaft an order to secure a roper engagement between the numeral w eel pinions and their actuating mechanism and automatically to raise the same shaft to insure a disengagement between such parts at the end of an enumerating and accumulating operation. I have devised a novel method of accomplishing this purpose, and one which is more simple in construction and more economical to make than that which has heretofore been so employed.

In the drawings, Figure 1 is a side eleva tion of a portion of an adding machine embodying my. invention with the numeral wheel shaft elevated and the main shaft not yet actuated; Fig. 2 is a similar view at the end of the forward stroke of the main shaft showing the numeral, wheel shaft lowered; Fig. 3 is a similar view showing the relation of the total key to the numeral wheel support; Fig. 4 is a detail edge view of some of the parts shown in Fig. 3; and Fig. 5 is a view slmilar to Fig. 3 but showing the parts in different positions.

In the drawings, 1 is the frame of the machine, 2 is the main shaft mounted in suit- F able hearings therein. Mounted on each side of the machine and secured'to the main shaft are cranks 3 and 4, each carrying rollers 5 The roller 5 on the crank 4 moves in a slot (3 in a lever 7, the other end of which is secured to a rocking shaft 8 arranged transversely across the machine.

The lever 7, shaft 8 and connected parts serve to actuate the accumulating and carrying mechanisms which form no part of the subject matter of this application but are described and claimed in co-pending applications. The roller 5 on the crank serves to engage the latch 27 hereinafter referred to. On each side of the frame of the ma chine are vertical recesses 9 adapted to receive the numeral wheel shaft 10 which reciprocates therein as hereinafter described.

Secured to and depending from the shaft 10 on each side thereof and outside of the frame of the machine are toggle links 11, each provided at their lower ends with outwardly extending pivots 12 to each of which is secured a toggle lever l3,which levers are loosely mounted on a fixed shaft 14 arranged across the machine.

It will be understood that numeral Wheels 15 arranged in denominational series are loosely mounted on the shaft 10. They are each provided with pinions16 and each actuated by segment gears 17, onefor each wheel, and which are loosely mounted on the transverse shaft 14c- The segment gears moved by control bars, indicated at 18, and fixed detents 19 serve to position the numeral wheel pinion 16 when they are not engaged by their respective gears. The manner of controlling and actuating the numeral wheels is explained in the applications for atents above referred to.

Secure to the pivots 12, one on each side of the machine, are operating levers 20, each provided with a slot 12 adapted to engage a pin 22 secured to the frame of the machine and supporting the lever against the force of gravity. A spring 23 secured to the pin 22 and to a pin 24 projecting from the lever tends constantly to move the latter toward the left in Fig. 1. 'II he lever is provided with a notch 25 adapted to serve as a catch to receive a latch pin 26 of a latch piece 27 mounted to oscillate on a pivot 28 projecting from the frame 1. It is provided with a tall 29 to which is attached a spring 30, the other end of which is secured to the frame of the machine and which tends constantly to move the latch pin 26 toward the lever 20. Depending from the tail 29 is a i stroke of the main shaft.

34 pivoted to the sector 36 between lugs 37.

A flat spring 35 securedto the sector 36 is adapted to press against the carrier 34 to keep it in the same vertical plane as the projection 32 on the lever'20.

Normally the numeral shaft is in its uppern' ost position and the pinions of the numeral wheels engage the fixed detents 19. In the operation of enumerating an item the keys of the machine are depressed and the control levers are moved to positions corresponding to the depressed keys and the segment gears 17, moving with them, are moved distances proportioned to the digits displayed on the depressed keys. These operations take place during the forward stroke of the main shaft and at the conclusion of such stroke the numeral wheel shaft should be lowered to bring the pinions of the numeral wheels into mesh with the segment gears so that as the latter are oscillated during the rearward stroke of the main shaft the wheels are rotated to accumulate the items enumerated. At the conclusion of such stroke the numeral wheel shaft should be again elevated in order that the parts should be ready for a new cycle of operations.

Normally and before the main shaft is oscillated, the parts are in the positions shown in Fig. 1 in which it will be observed the numeral wheel shaft is elevated, the toggle links and levers are in a vertical line, the lever is at its extreme position to the right and is held against the tension of its spring 23 because the latch pin 26 is in the notch 25. When the main shaft 2 is oscillated, at the end of its forward stroke, the parts assume the positions shown in Fig. 2.

The rollers 5 on the ends of the cranks 3 and 4 are brought to contact with the under surfaces of the members 31 of the latch pieces 27 and simultaneously lift the latter disengaging the pins 26 from the notches 25. The moment this disengagement. takes place the springs 23 quickly pull the levers 20 toward the left moving with them the toggle links 11 and toggle levers 13 causing the numeral wheel shaft 10 to descend to the bottom of the recesses'9, when the numeral wheel pinions 16 will at once be in proper mesh with the teeth of the segment gears '20; This engagement of the numeral wheel pinions and their gears remains until the end of the rearward stroke of the main shaft when the roller 33 mounted on the carrier .34 is, by the oscillation of the sector 36, brought to contact against the'left edge of the projection 32 of the lever 30 bodily moving the latter toward the right, stretching the spring 23, straightening the toggle links and levers and thus elevating the numeral wheel shaft, until the latch pin 26, under the influence of the spring 31 and of gravity, falls into the notch 25 and thus maintains the parts in their normal positions.

When a total is to be recorded on the machine it is necessary to cause an immediate engagement between the numeral wheel pinions and their segment gears at the beginning of the forward stroke of the main shaft in order that the wheels shall be rotated backward during such stroke. To that end the numeral wheel shaft must be immediately lowered at the beginning of such strok I A totalizing key 40, provided with the usual tip 41 and the stem of which is slotted at 42 to engage a guide pin 43 projecting from the frame of the machine, is pivoted at 44 at its lower end to a longitudinally arranged total lever 45 which is secured. to a cross shaft 46 to which in turn are secured two upwardly extending levers 47 provided with forks 48 adapted to engage the pivots 12 of the toggle links and levers. A link 50 connects the tail 29 of the latch piece 27 with the lever 45, a pin 51 on the link 50 and a slot 52in the lever 45 permits the latch 27 to be moved by the roller 5 without affecting the lever 45 (see Fig. 2). A spring 53 secured to the lever 45 and to a fixed point on the frame serves, constantly, to keep the totalizing key up. This spring is not, however, as strong as the spring 23. A roller 54 mounted on a pivot 55 projceting from the lever 45 is adapted to engage the curved surface of a latch arm 56 pivoted at 57 to the sector 36 and constantly drawn toward the right by a spring 58. The latch arm 56 is provided with a latch finger '59 projecting toward the right. On the face of the sector 36 is a circular flange 60 provided with a terminal cam face 61 at its right end and a locking face 62 at its left end. On the side of the stem of the totalizing key 40 is a lug 64 provided with a vertical straight surface 65 and a sloping cam surface 66. This is adapted to engage and cotiperate with a projection 67 on the carrierr 34 as will presently be explained.

When the totalizing key 40 is depressed the lever 45 is moved downward and the forked levers 47 are moved upward to ongage the toggle joint pins 12, the link 50 is pulled downward, the latch piece 27 is oscillated and the pin 26 is disengaged from the notch 25, whereupon the spring 23 moves the lever 20 toward the left so that the and at'an angle to each other and the nomeral wheel shaft descends to permit the numeral wheel pinions to engage their respective gears. Practically simultaneously with this operation, as the totalizing key stem is depressed, the roller 54 moves against the latch arm 56 passing by the locking face 62 of the flange 60 on the sector 36 and over the tip of the finger 59 until it is beneath the latter where it remains. At the same time, the sloping surface 66 on the lug 64 of the totalizing key.40 in its downward movement has engaged the projection 67 on the carrier 34 and moved the latter out of the plane of movement of the lever 20 (see Fig. 4) to allow the latter to move to the left. The parts are now in the position shown in Fig. 3. The main shaft being oscillated the lower edge of the circular flange 60 is moved over the roller 54 which, until that time, has been held by the finger 64. flange 60 holds the total key depressed during the forward stroke of the main shaft. At the end of this stroke the circular flange 60 will have entirely passed the roller 54 (see Fig. 5) and, under the influence of the spring 53, the lever 45 will be slightly lifted so that the roller 54 will mount to the cam surface 61 of the flange 60 and, during the rearward stroke of the main shaft, the upper surface of this flange 6O positively lifts the roller 54 and lever 45, and the latter, acting upon the forked levers 47, straightens the toggle joint and lifts the numeral wheel shaft to its normal position, at the same time charging the spring 23. The reengagement of the pin 26 with the notch 25 on the lever 20 is permitted by the movement of the lever 45 allowing the link 50 to rise under the influence of .the spring 30. The total key 40 is simultaneously lifted also to its original position. In the operation of taking a subtotal, the numeral wheels are brought into mesh with the actuating racks upon the first movement of the handle and are kept in such relation during the movement of the handle throughout both backward and forward strokes. The particular mechanism employed for this purpose is not shown in the drawings, as it is well known in the art and forms no part of the present invention. Such mechanism is disclosed, for example, in patent of Mc- Farland, No. 842,232, issued January 29, 1907.
